KWX Current Sense Resistors FLP

Product catalog summary

Overview: The document provides technical specifications and guidelines for FLP series current sense resistors, which are designed for applications requiring low inductance and high precision, such as current sensing and feedback.

Features: The resistors are constructed with welded points and flameproof materials, featuring solderable tin-plated copper leads. They have an inductance of less than 10μH.

Specifications:

Power Ratings: Available in 1W, 2W, and 3W at 85°C.
Resistance Tolerance: Options include ±1% (F), ±2% (G), ±3% (H), ±5% (J), and ±10% (K).
Temperature Coefficient of Resistance (TCR): ±20 ppm/°C.
Temperature Range: -55°C to +325°C with derating as per the provided curve.
Voltage Rating: Calculated as Power (P) x Resistance (R).

Dimensions: The resistors come in three types (FLP-1, FLP-2, FLP-3) with varying dimensions and weights based on resistance values.

Performance Characteristics:

Full power dissipation at 85°C, linearly derated to zero at +325°C.
Short Time Overload: 5x rated power for 5 seconds with specified resistance change.
Damp Heat: Tested at 40°C and 93% relative humidity for 1000 hours.
Endurance: Load life tested at 70°C with limiting voltage for 1000 hours.
Resistance to Soldering Heat: Tested at 260°C-270°C for 10 seconds.

Applications: Suitable for current sensing, feedback, surge, and pulse applications.

Standards: Complies with IEC 60115-1 and IEC 60068-2-20 for solderability.

Catalog excerpts

Note : Resistance values must be checked using 4 1/2digit micro ohm meter with four wire system and insulated clips, which should be attached to the resistor leads over centered length “LM" in the case of FLP series. In differing conditions, please compensate by ± 0.4m 0/ cm. 0 Ordering Information Example: FLP-1 1 F R01 C Series Name Power Resistance Resistance ( ) Rating Tolerance Value TCR
